Villegas hauled back a five-shot deficit to clinch the title

Camilo Villegas clinched the season-ending Tour Championship in Atlanta after defeating Spain's Sergio Garcia in a sudden-death play-off.

The Colombian carded a five-under round of 66, while overnight leader Garcia saw his three-shot advantage evaporate after three bogeys in 10 holes.

Villegas, 26, won his second successive PGA Tour victory with a par three on the 18th, which Garcia bogeyed.

Phil Mickelson and Anthony Kim finished one shot back on six under.

Villegas claimed his first title at the BMW Championship three weeks ago after going 85 tournaments without a win.

"This is unbelievable. I cannot emphasize how hard I have worked and my team has helped me," he said.

Garcia had been seeking to become the first player since 1990 to win the Players Championship and Tour Championship in the same year.

But the 28-year-old suffered yet another defeat to follow on from his Ryder Cup anguish from Valhalla.

"I just didn't play well enough," he said after hitting only five out of 14 fairways. "I doubted myself too much early on and it cost me.

"I just didn't commit to my shots the way I should have, and then I paid the price.

"I lacked a bit of commitment. The freedom that I've been having with every part of my game, it wasn't there early on."

Garcia began the day with a five-shot lead over American pair Anthony Kim and Phil Mickelson, but it was Villegas who made the biggest impact on Sunday.

He holed eight birdies during his round - which included a double bogey at the sixth - to haul his way past the American duo to the top of the leaderboard.

And he forced the play-off when Garcia failed to birdie the 18th with a tricky 20-foot putt.

Mickelson, the 2000 champion, had a chance of joining the play-off but narrowly missed a 20-foot birdie putt at the last.

The left-hander tapped in his par putt for a 69 and a share of third place at six under with compatriot Anthony Kim (69).

Fiji's Vijay Singh won the season-long points race for the FedExCup by signing off with a level-par 70.

He had all but secured the trophy after winning the first two play-off events and simply needed to complete Sunday's final round to pocket $9m in cash with $1m deferred.

"I played well and I'm glad this Cup is over. I know it's mine now so it's a good feeling," said Singh.
